Pretty much the same here. I'm happy with my lifestyle, I don't really long for anything I don't have (or can't have), so I doubt a pile of money would be "life-changing."
More money might change the
way I do some things, but probably not the things themselves, so I don't think my lifestyle would change radically. Maybe I'd fly a newer, fancier plane, but I'd still fly. Maybe I'd stay in 5-star hotels instead of 3 or 4-star when I travel, but I'd still take the same trips. Maybe I'd have a couple of more cars, but I can only drive one at a time anyway. I would do more
pro bono projects with Engineering Ministries than I do now, but two a year is about the practical limit anyway.
About a decade ago, Wes Moss wrote a book called
You Can Retire Sooner Than You Think.
https://www.amazon.com/You-Retire-S...t=&hvlocphy=9060296&hvtargid=pla-493259108818 . One of the really interesting tidbits in the book was a study that Wes did which involved surveying retirees and asking them to rate their degree of happiness. He found that happiness does increase with the size of one's nest egg,
but only to a point. The increase in happiness levels off, and it does so much lower than you might think.
Now this graph is dated, and no doubt the dollars would be higher today, but maybe not that much.
Once a person reaches the point where they can do the things they enjoy (travel, dining out, flying, charity work, whatever) at some level, they enjoy life. When they're not able to do the things they want, they're frustrated and unhappy.
IMHO, one of the keys is to understand oneself and what's really at the core of the things you enjoy. Once you understand that, you can find ways to satisfy yourself at a financial level you can afford. For example, I really love high performance vehicles, the acceleration and most especially the handling. A Ferrari or Lambo might be a blast, but would be a stretch financially. I can (
and do!) afford a sport bike that matches or beats that car performance, and costs a small fraction as much. I'd bet I have at least as much fun on my Triumph Daytona as I would in a Ferrari, and the bank account didn't even say "ouch," much less "boing."
In my younger days, acquiring a pile might have made a bigger difference if it let me clear debts and stop working. But would life have been better? I doubt it.
